In Czechoslovakia November 8, 1948 5 Claims.

and one object of the invention is to provide an improved basin which facilitatescleansing and clearing operations.

According to the invention a sanitary closet basin is provided with an outer shell, a removable inner bowl, and a removable bell which fits inside the'shell, the bell and the shell being mutually complementary so as to form a discharge Siphon and a water-trap. Preferably part of the wall of the Ibell is arranged to provide inlet and discharge ports for the water-trap. In an advantageous construction the shell comprises a discharge conduit and part of the lower edge of the bell lits around part of the upper end of the discharge conduit. The above-mentioned features and further features of the invention are to be perceived by studying the following description of a basin according to the invention and the following claims.

In the accompanying drawings one sanitary closet basin according to the invention is illustrated by way of example,

Figure 1 being a sectional side elevation of the basin,

Figure 2 a plan View of the basin,

Figure 3 a sectional view of a detail,

Figure 4 a front sectional elevation of the basin, the section being taken half on the line IVA-IVA and half on the line IVB-IVB of Figure l,

Figures 5 and 6 sectional views of the flushing nozzle, and

Figures 7 and 8 a sectional View and front elevation respectively of a cover plate.

Referring to the said drawings, the basin com prises an outer shell I which is formed as a pedestal. A discharge conduit 2 is formed integrally with the shell I and has an upper edge 3 located so that water is trapped in the lower part of the shell I. Around part of the upper end of the conduit 2 there is formed a seat 4 on which rests a bell 5 having a lower edge 6 in contact with the seat il. A pivoted handle 'I is provided on top of the bell 5. One wall of the bell 5 extends downwardly and thereby provides an inlet port 8 and a discharge port 5 for the water-trap. The bell 5 and the conduit 2 together form a discharge Siphon. A removable inner bowl I2 is arranged within the shell I and has its lower edge II resting on an internal ledge I in the shell. The bowl I2 has a discharge opening I3 which corresponds with the inlet port 8 of thewater-trap. A supporting rim Iii is secured by bolts I to the upper edge of the bowl I2. Through an aperture at the rear of the bowl I2 projects a :flushing nozzle I6 which is secured in its place on the shell I by means of a cover plate II which is fixed to the shell I by bolts I8. Two trunnions I9 are provided on the plate Il and in the rear parts ofthe bowl I2 are slots 2@ to accommodate these trunnions. A seat 22 is connected by a hinge 23 to a plate 2| which is xed by screws 24 to the plate I'I. I v

From the above description it will be clear that the inner bowl I2 togetherA vwith the supporting rim I4 can be swung upwardly about the journals or trunnions I9 to assume a position which is partly indicated by dotted lines in Figure 1. By means of the handle I the bell 5 may be lifted out, and then all the surfaces ofthe shell, the bowl and the bell are accessible for cleaning. The interior of the conduit 2 is also accessible, and this facilitates clearing the conduit or the pipe below it should anything become lodged therein. The slots 20 permit the bowl I2 to be lifted off the trunnions I9. A further advantage is that if the bowl or the bell become damaged or defective it is easy to remove them and to insert a replacement.

Various modifications may be introduced without departing from the invention as claimed below, for example the inner bowl and the supporting rim may be formed integrally with each other.
